Горизонтальная гипсовая Порошковая печь линия по производству гипса вращающаяся для гипсового порошка

Product introduction and application

 This series of rotary kiln is the large-size advanced international calcining kiln & furnace which is developed by our company and many scientific research institutes such as Beijing General Reserch Institute of Mining & Metallurgy, Changsha Research Institute Of Mining & Metallurgy, Suzhou Sinoma Reserch Institute of Non-metallic Mining Industry, etc. Compared with the rotary kiln with the same specification made by the traditional technology, this series of torary kiln can make the production capacity increase by 30%, make the heat consumption reduce by 40% and make the discharged flue gas temperature<250 °C , so it is convenient for collecting dust and meeting the modern environment protection needs about energy saving and consumption reducing. This rotary kiln is widely used for extracting nickel from laterite, calcining the activated limestone, oxidized pellet, magnesium oxide, aluminum oxide, titanium dioxide, etc.

Advantage Of Rotary Kiln

1.High Automation Level
Its pre-heater with low-pressure loss can improve preheating effect efficiently. After preheating, the resolution ratio of the lime-stones can reach 20~25% when they enter the kiln. Besides, the lime-stones, with fine fraction about 10~15mm, can be used directly.
2.Waste Heat be Reused Effectively
The two sides of the reliable rotary kiln are sealed by the combined scales, which can make the air leakage coefficient less than 10%. Composite refractory materials should be used in order to reduce the loss of radiant heat.
3.Low Energy Consumption
The filling vertical cooler, round or square, can be zoned-ventilation, which can make the temperature of lime-stones in the cooler at about 80°C. As a result, it is very convenient to transport and store. It can also pre-heater the secondary air up to the temperature above 900°C, then the waste heat can be recycled to reduce energy consumption.

Working Principle 

Derui Rotary kiln cylinder composed of steel plate, cylinder body with build by laying bricks or stones of refractory lining, and horizontal line into slope, three belting leather in each block supporting device, in the material near the end belting leather across the inner cylinder with tangential spring plate fixed on a big gear ring, which is a small gear meshing. During normal operation, the main drive motor is transmitted to the open-type gear device by the main drive motor, which drives the rotary kiln.Materials are calcined from the end of the kiln. Due to the effect of tilting and slow rotation of the cylinder, the material is along the circumference of a circle and tumbling along the axial direction (from high to low) mobile, continue to complete the process, and generate the clinker kiln hood into the cooling machine cooling.The fuel is sprayed into the kiln by the kiln head, and the waste gas and materials produced in the furnace are exchanged for impact crusher, which is exported by the kiln tail.
